Garhauer Davit setup questions

[Doryman]

This is primarily for Bob but if anyone else has a Garhauer Davit please jump in!

Here is a photo of my Davit after the mount was rigged on my boat (obviously it is off the boat for the photo):



When I looked at the Davit in the Thataway album, I could not tell if Bob's had the block on the standard of the Davit or not. But it seems to me that it is on the wrong side of the standard. That way the line would go through the lifting block and tackle, over the arm, through the cam cleat and down the outside of the standard. If that is the case, then how would one utilize that one-pulley block because in order to release the line from the cam cleat you would have to yank it out of the cams -- which you could not do if it were threaded through the small block.

Another question relates to the bracket that supports the arm. It is held in place by a bolt and nut, which seems like an invitation to lose a piece overboard. Have you replaced that bolt and nut with a wing not or something similar?

Thanks,
Warren

Warren,
I also have a version of the Garhauer davit like yours--not sure if it is the longer arm which has this--or if all come this way now. Anyway, the davit can be utalized two ways. One is the way which you have rigged (mine has a jam cleat also just below the turning block on the support) and the second way, is the way it is rigged in my photos, where the line comes back thru the arm to the jam cleat on the top of the arm.

I carry a spare nut, but in using Garhauer davits for about 5 years, I have yet to loose one of the nuts or bolts.

 

[Doryman]

Through a mixup with Garhauer I ended up with both arms. I think I will rig it like yours so I can use the cam cleat.

I wondered how much weight can one of those davits handle. Secondly not that it's really any of my business but what do you use them for? I could only think of putting a motor on the dingy. As long as I am asking stupid questions what's a gypsy; in relation to a windless and anchoring. I know about the ones usually seen wearing baggy shirts and bandannas. The dictionary was not much help I googled it and you can't imagine. I really didn't want to ask this but I've owned five boats and never knew what the term was actually referring to.

The gypsy is the cogged wheel around which the rode is played out or in. Gypsies are a little persnickity about the size and type of rope or chain and there is a springloaded arm called (I think) the fleming that acts to hold the rope/chain onto the gypsy.

I recently installed a garhauer lifting davit on my CD25. I mounted it on the port gunnel at the back edge of the cabin. I plan to use it for launching and retrieving the dinghy from the roof. Also, with the addition of an open faced pulley, to retrieve crab pots. After installation my son and I tested it by lifting him off the ground. He weighs about 200lbs. I did add the support bracket, also sold by garhauer, to give extra support. I really like the idea that it is removable and compact when disassembled. I replaced the nut and bolt that secure the arm support to the upright with a lock pin from the local tractor dealer. That allowed me to tether the lock pin to the arm support. I think it will be a great addition to the safety and convienance of using the dinghy.

There is a little confusion about the use of Gypsy, Wildcat, and Chain wheel--they are basically all the same thing. Gypsy is used in Europe more. It has become more common to call the combination chainwheel/rope wheel a Gypsy. A chain wheel is specific.

A warping drum is the capstan head or drum which takes rope only, and has no chain indentations.

We lift outboard motors from the kicker bracket to the dinghy, lift the dinghy off the boat and onto the dock, we lift the generator from the box in the cockpit to the motor bracket or spash well mounting (bad backs), we even use it to lift ice boxes aboard. We also use it to haul the dinghy aboard and stow it. Although the Garhauer davit is not designed for lifting people, in an emergency we would use it to get a person aboard.

All of this happens because one gets old--but maybe the back problems could be prevented by using hoists when we are younger!

Secondly not that it's really any of my business but what do you use them for? I could only think of putting a motor on the dingy.

Yes, for for mounting the motor on the dinghy, and also as an experiment I have set up the swim ladder bracket as a motor bracket so I can put the 3.5 hp Tohatsu on the bracket and troll ultra-slow. It may not work, but it was worth a try, I thought. So I will use the davit to swing the motor into position for that as well.

I'm also going to use it for moving my generator from the cockpit to the swim step if I feel I need the help. (I don't have a bad back like Bob but leaning out over the water with a 40# outboard and no support doesn't seem too smart to me.)

I plan to use it for launching and retrieving the dinghy from the roof.

That was my original idea but when I had the boat at EQ they could not figure out a way to make it work with my TC255 even with Bob's photos as a guide (maybe because I have a radar arch with rocket launchers aft on the cabin top). Les is going to install a custom davit for the dinghy that he is having built for his Rosboroughs.

II did add the support bracket, also sold by garhauer, to give extra support.

I am not familiar with that support bracket. Are you talking about the collar that the standard slides into?

II replaced the nut and bolt that secure the arm support to the upright with a lock pin from the local tractor dealer. That allowed me to tether the lock pin to the arm support. I think it will be a great addition to the safety and convienance of using the dinghy.

Good idea -- I will likely do the same.

Warren,

Glad you clarified why you need the custom davit. I automatically thought it was for hauling in those Salmon derby winners :lol:

Warren,
To describe the additional support, it is a 10inch piece of 1 inch SS tubing with a clamp bracket welded to one end. After cutting to length there is a sleeve that goes on the support pipe. Where mine is mounted on the port gunnel at the back of the cabin I was able to clamp the support to the port grab handle on the back of the cabin. The locking pin from the tractor dealer is a straight pin with a C shaped spring locking clip.
The locking clip looks like a heavy wire. The locking clip will, when sized
correctly, wrap around the upright support and secure the pin. Hope this is better explanation

 

[thataway]

I think that GOYO is describing a "stand off" --which allows the aluminum 2" sleeve to be clamped to a remote railing or stenchion post. I just bolt my sleeves to the fiberglass , after flattening the "U" which goes around the railings.

GOYO do you mount the ball on the top of the gunnel--and if so, does it interfere with walking on the deck or going into the cockpit? Do you have photos (Album?)

I will be drivng by the factory in a week, and was thinking of getting an extension for the davit made, to make it taller--That is one of the reasons for the mount on the side of the cabin--to put the top up high enough to bring the dinghy up there.

That is how EQ set up mine. Easier to show in a photo. I need to document all the refit mods I had done for the photo album. Will do that soon.

On Garhauers website they show the lifting davit in 2 different places, with slightly different descriptions. One of the descriptions has the additional support bracket as an option. It is all stainless tubing and clamps. It is designed to be cut to length for the application. I believe it is designed to attach to a rail for added upright support. I mounted the ball on the port gunnel on top of the raised area at the back edge of the cabin. While it is on the walkway, that area being raised is not a place where I would step as there is no antiskid on it. It puts the upright for the lifting davit parallel to the back wall of the cabin. I will try to get some pictures of the install posted.

Warren,

Thanks for starting this thread. It has inspired me to drag my Garhauer lift out of storage and install it on the TC. We used it for lifting a 115# outboard onto a dinghy 2 boats ago. The line on mine travels down the top of the extension arm and through the cam cleat.

Today I drilled the holes out to 1/2" and reassembled it using Pit-Pins. I figure it will knock down easily that way and store in a bag about the size used for a folding chair. I have had to wrestle an exhausted diver aboard and wish I had the lift installed then. Not sure yet where I'll mount it but will post again when it's complete.

 

[Doryman]

Pit-Pins

What are these? Where can I get them?

EQ mounted my davit outside the cockpit, on the Armstrong Bracket, about halfway from centerline to edge. They installed a SS bar from the swim step grab bars to the railing, and on that bar they attached the collar. Will post photos too.

Warren,

Here's a photo of some Pit-Pins. You can see the metal balls near the tapered end. They extend out just far enough to prevent the pin from being removed from a hole that's just barely larger than the pin shank. When the button on the handle end is pushed in, the balls retract and the pin can be removed.

They're used primarily in military and aircraft applications. They're hard to find. Surplus stores may have some.

The support bracket I used is listed on the Garhauer website under radar tower accessories. It is the last item listed.

Warren,

For those pins, try: http://www.mcmaster.com/

Search for: Push-Button Quick-Release Pins

Note that most of the pins shown are available in stainless.

In fact McMaster-Carr is a good source for all sorts of generic stuff applicable to working on a C-Dory. When you see the index, you'll know what I mean.

Ball-Lok Quick Release Pins are available in stainless steel for marine applications, and often used on sailboats. They're pretty expensive. If you can find a military surplus type of store, they often have non-stainless ones for a lot less.

The best kind have a raised guard around the release button to guard against accidental release. This surrounding guard has a hole drilled along one edge of it to attach a seizing line so as to securely attach the pin somewhere near where it's used so that the pin doesn't become lost.

Ball-Lok- Quick Release Pins Note correct spelling is not "Lock".
